EDWIN E. BARNEY, OF SYRACUSE, NEW YORK, AssreNoR To THE MONAROH TYPEWRITER COMPANY, OF SYRACUSE, NEW YORK,.A CORPORATION OF NEW YORK.

TYPE-WRITING MACHINE.

To all whom it may concern: I j Be it known that I, EDWIN E. BARNEY, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga and.

State of NewvYork, have invented certain new and useful Improvements in T This invention relates to typewriting machines and more particularly to the type bar actuating mechanism of such machines.

The main object of the invention is -to provide an improved construction 'of joint orconnection etweencertain of the members of the type bar actuating mechanism.

Other objects will subsequently appear.

' To the above ends my invention resides in thefeatures of constructlon, arrangements of a skeleton view inside elevation of a type 'bar and its actuating mechanism. Fig. '2 is f Fig. 4 is an enlarged detail view showing the rear end of a connecting link.

In the drawings, 1 indicates a fulcrum plate attached to the frame 2 of the machine,

3 one oi a series of key levers slotted at 4 so as to embrace a fixed bar 5 and each provided with a restoring spring 6 and key cap 7. i A sub-lever 8 is pivoted at 9 to each key leverand the lower end of said sub-lever is slotted or recessed at 10 in order to co-act with a fixed fulcrum rod 11 which passes from side to side of the machine, beneath the series of key. levers. The ppp in a manner resently to be more fully described. Eac type bar is provided with a type block 14 carrying one or more types. The free ends of the series of type bars are normally supported by a type rest 15 and the types are a apted to-strike against the face of a laten 15. At its pivotal end, each type ar is seated'in a slot 16 formed in a segmental t e bar support 17 which slot is one of a radia y arrangedseries, and the heel of said type bar is perforated to permit of the ass'ege' of a-fulcrum. wire 18 which is secured 1n the top of the type bar support 17 I-do not desire to be limits .to the particu- Specification of Letters Patent.

lar construction of pivotal support for the type bar as shown and described; other styles of support may be employed equally as well. It will be apparent that the construction and arrangement of parts as hereinbefore set forth is similar in most respects and may be said generally to be that of the Monarch typewriting machine, but my invention may be adapted and applied to other forms of writing machines.

, Referring now more particularly to the novel features wherein my invention resides and consider'ng especially Figs. 2 and 3, each connecting link 12 has secured at its rear end a pin 19 which rojectsjfrom the side of said link at right ang es to the body portion thereof andterminates in a circular head 20, the end or lower portion of said head being flat- At its top, each sub-lever 8 is forms with a vertical tened or cut away at 21 (Fi 4).

elongated slot 22 larger in diameter at the bottom than at the to and which, for convenience, will be calle a key-hole slot. Secured to the sub-lever below the key-hole slot in any suitable manner as by a rectangular rivet 23 is a flat locking s ring 24., the free end of which is bent inwar at 25 so that it normally stands within the key-hole slot and terminates at a distance below the top of said slot slightly greater than the diameter of the pin 19.

'B this arrangement under any stress ten ing to withdraw the pin 19 from the keyhole slot the under side of the head 20 of said pin is caused to engage with the face of the sub-lever 8 above the top of the key-hole slot and thus the link is prevented from being actype bar ,and its connecting link may be of any desired construction.

In practice, the type bars and their associate lihks. are assembled before being secured in place on the type barsupport 17,

and the key levers and their associate sub levers are separately assembledand mountedthe sub-lever 8. The joint 27 between each I to , by Letters Patent, is r key-hole slotand the other with a headed in adapted to enter the'wider part of said s 0t;

' vention.

parts and adapted to maintain the headed in the machine. The pin 19 on each connecting link or member 12 will now be snapped into place in the key-hole slot in the-sub-lever, and the type action is thereby completely assembled. Taking the steps of what may be called the snapping in process in order:

the pin 19 is first passed through the wider" portion of the"key-hole slot 22 of its associate sub-lever or actuating member, the head 20 of said pin pushing the spring 24 away from the face of the sub-lever; next the pin 19 is liftedto the upper narrow portion of said slot and over the free end of the spring and thus locked in place by the latter, which snaps back into normal position. The cutaway 21 in the head of the pin 19 enables the top of the locking spring 24 to be arranged close enough to. the top of the key-hole slot to permit a snug fit of the pin 19 to be obtained,

thereby preventing looseness and rattle in the connection." Y
